“Basically, science concludes that the more kind you are, the more sex you will be gifted,” the video says, showcasing a handy line graph that demonstrates as much.

For example, one study from the University of Guelph and Nipissing University asked about 800 people about their sexual history and how likely they were to engage in selfless acts like charity work, helping people across the street, and donating blood. Researchers discovered that those who were more altruistic had more success in the sex and dating department than those who were more selfish.

In another study, more than 500 college students were asked about their sexual participation and asked a question designed to measure their level of altruism. The question: “If you won $100, would you give it all to charity, keep all of it, or give some of it to charity?” Like the other study, this one concluded that those who were deemed to be more kind had a higher history of casual sex, long-term relationship sex, and marital sex.

What’s up with this? It’s likely due to the fact that historically, women have been more attracted to men with resources who are also generous with their stuff. (Think: Cavemen who are good hunters, who are also down with sharing their mammoth meat.)

Researchers say that the notion that women are attracted to bad boys is B.S. Rather, women are into confidence, which many bad boys possess (or at least pretend to possess). But women are also attracted to ambition, humor, kindness, intelligence, and emotional availability. (In fact, women would rather date nice guys than good-looking men.)

Bottom line: You’re better off being a nice guy.
